It stands for "Artificial Intelligence. There are two main types of artificial intelligence: specialized artificial intelligence, which specializes in one thing, and general-purpose artificial intelligence, which can do a variety of things. Specialized artificial intelligence can only perform specialized tasks, while general-purpose artificial intelligence can think and apply itself based on given information. However, it is said that there is still a long way to go to realize AI that can perform multiple tasks with the same level of intelligence as humans.
With the advent of deep learning, a type of machine learning that automatically extracts features from data for classification and prediction, it is now possible to increase accuracy in areas such as image recognition, voice recognition, and prediction technology.
